The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, mining method and the composition and stability of the bedrock. The ratio of waste rock/ore is called stripping ratio. For example, a stripping ratio of 21 means that 2 tonnes of waste rock needs to be removed to mine 1 tonne of ore.
